HENRY W. MATALENE, OF NEW YORK, N. Y.

PENDANT CONSTRUCTION FOR WATCHES.

Application filed March 15, 1912.

To aZZ whom it may concern.

Be it known that LHENRY W. MATALENE, a citizen of the United States, residing at lx ew York, in the county and State of New lork, have invented new and useful 1mprovements in Pendant Constructions for ll atches, of which the following is a specitication.

This invention relates to the pendant,bow and sleeve, and parts immediately associated therewith, of watches employing the socalled American system of setting, and is intended to improve upon prior constructions of the parts in question in certain respects which will hereinafter appear, my improvements being illustrated in their pre terred form in the accompanying drawings, in which Figure 1 is a central vertical section through the pendant and associated parts at the top of the watch case, with the bow and winding bar shown in elevation; and

Figs. 2 and 3 are transverse sections on the lines 2-2 and 33 in Fig. 1, respectively, Fig. 3 being drawn to a larger scale than the other figures.

In the drawings, 2 represents the base portion of the pendant of a watch case, and 3 represents a cap piece applied to the top o1 the portion 2, the parts 2 and 3 constituting the complete pendant and being provided with a central vertical perforation t to receive the winding bar and other parts hereinafter described. The meeting faces of the parts 2 and 3 are preferably flat, and extending inward from the outer edges thereof at diametrically opposite points are cylindrical bearings 5 arranged in axial alinement with each other and terminating at their inner ends in recesses 6 of larger diameter, these bearings and recesses being formed one-half in the top of the portion 2 and the other half in the bottom of the cap-piece 3, as shown in Fig. 1. The bow of the watch, indicated at 7, has its end portions turned inward toward each other and arranged in axial alinement, and at its ends it is provided with heads or enlargements 8 located in the recesses 6, while adjacent to said heads the end portions of the bow are formed and arranged to fit and rest simultaneously in the cylindrical bearings 5, in which they turn. All possibility of the pulling out of either end of the bow is thus prevented unless the cap piece 3 is first removed, and for securing said cap piece to Specification of Letters Patent.

Serial No. 683,980.

the portion 2 I provide a hollow bolt 9, which is screwed into the upper portion of the opening l and has an enlarged upper end bearing upon the top of the cap piece 3.

The crown for operatii'ig the winding stem is shown at 10, and has downwardlyextending shank which passes into the hollow bolt 9 and is attached at its lower end to the upper end of the winding bar 11. Said bolt 9, therefore, cannot be unscrewed from the pendant, either intentionally or accidentally, without first removing the crown 10, which in the form shown in l is recessed on its under side to receive the top of the bolt and is also shaped to enter and fit a depression in the top of the cap piece 3, whereby the bolt is wholly concealed from view and the parts are given a tinished, compact and attractive appearance and contour.

The winding bar 11 which extends down from the crown 10 in the hollow interior of he portion 2 is of the form usually employed in watches 01 this general character, being provided at its lower end with an angular portion 12 adapted to enter a correspondingly-shaped stem socket in the watch movement not shown), and being also provided above said angular portion with an out-wardly-rounded enlargement 13 adapted to cooperate with the sleeve 14;, hereinafter described, to hold said bar in either the winding or the setting position. Below the enlargement 13 the bar 11 is provided with a flange 15 adapted to abut against the lower end of the sleeve 1% and serve as a stop to limit the outward movement of said bar when pulled into setting position. The sleeve 1% is substantially cylindrical in form, and is provided with slots 16 extending upward from its lower end, whereby spring arms are formed the free ends of which are adapted to pass over the enlargement 13 and grasp the bar 11 either above or below said enlargement in the usual manner. Said sleeve, however, instead of being screwed directly into the pendant as has been the common practice heretofore, is carried in the present case by the bolt 9, and is preferably connected there to somewhat loosely, by having its upper end shaped to provide an outwardlye. :tending annular rib 1'? which is located in a correspondingly shaped recess formed in the lower end of the bolt 9. Just above the sleeve said bolt is provided with an inwardly-extending flange 18 to serve as a positive stop for preventing upward movement of the sleeve, and its lower edge is bent inward beneath the annular rib 17 after the bolt and sleeve have been assembled, leaving the sleeve free to move laterally to a slight extent and thus accommodate itself exactly to the position of the bar 11 when the latter is fitted into the stem socket of the movement. As thus constructed, the bolt and sleeve are inserted and removed as a single piece, and when the parts are in assembled relation the sleeve is absolutely prevented from getting out of place by its connection with the bolt, which in turn is securely held against being unscrewed as already described. There is thus provided a simple, practical and durable construction of the pendant, bow and sleeve whereby these parts are maintained in their intended position with certainty and without making it necessary to employ special locking devices or other mechanical features which would tend to complicate the construction and increase the size necessary to be given to the pendant, which according to the prevailing style in watches should be kept as small, as possible, and it is also an advantage of the described construction that it is dust proor', since the top of the hollow bolt, through which alone any dust could enter, is received within and efl'ectively covered by the recessed crown.

I claim as my invention 1. In a watch case of the character described, the combination of a pendant comprising a hollow base portion and a separable cap piece, a hollow bolt passing through the cap piece into the base portion Copies of this, patent may be obtained for of the pendant and provided at its lower end with an annular recess and with a stop flange above the same, a sleeve attached to the lower end of the bolt and insertible and removable therewith, the upper end of said sleeve being loosely mounted in the annular recess in the bolt immediately below the stop flange thereon, a winding bar passing through the sleeve, a crown secured to the upper end of the winding bar, and a bow having its end portions journaled between the base portion. of the pendant and the separable cap piece.

2. ln a watch case of the character described, the combination of a pendant comcrown overlying the top of the bolt and hav-' ing a downwardly-extending shank rotatably mounted therein, a winding bar secured to the crown and passing through the sleeve, and a bow having its end portions journaled between the base portion of the pendant and the separable cap piece.

In testimony whereof, I have hereunto subscribed my name this 13th day of March, 1912.

HENRY W'. MATALENE.
